The Chrysler Executive Sedan uses H4651 bulb size for high beam headlight and H4656 or H4652 bulb sizes for low beam headlight applications. The replacement chart covers 1983 to 1984 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H4651, H4656, and H4652 bulb types specified for the Chrysler Executive Sedan are all ANSI-standardized sealed beam units recognized in both the United States and Canada.
All three sealed beam types share a 4x6-inch rectangular form factor and operate on a 12V electrical system.
Sealed beam units of this type do not contain a replaceable bulb element; the entire unit is replaced as a single assembly when the light fails.
The H4652, used as the 1983 low beam, is a variant of the H4651 rather than a wholly distinct design, though the two types serve different beam functions and are not interchangeable in application.
The 1984 model year introduced the H4656 for the low beam position, replacing the H4652 used in 1983, meaning the two model years differ in their low beam specification despite sharing the same high beam type.
The high beam position uses the H4651 across both the 1983 and 1984 model years, indicating no change in that specification between those years.
